 view of posterior part of body, showing the two tufts of gill 

 filaments. Larva No. i of Text, x 6. 



Largely yellow ventrally, the marginal dots the only 

 conspicuous markings. 



Convex above, beneath concave, the body proper ele- 

 vated, and the head free, with a pair of slender yellow 

 antennae and dark eyes. Legs strong, not reaching beyond 

 the expanded terga, and thus giving the insect an appear- 

 ance of being legless when viewed from above. Just pos- 

 terior to the third pair of legs on each side are several tufts 

 of long white respiratory filaments. Ten somites appear to 

 be outlined in the terga, with median anterior and posterior 

 plates added. Length 7—9; diameter 4.7—7.6 mm.
